GEORGE W. GWINN, OF BROOKLYN, NEW YORK, ASSIGNOR TO AUTOMATIC PACKING & LABELING COMPANY, OF DURHAM, NORTH CAROLINA, A CORPORATION OF NORTH CAROLINA.

CAN-SPOUT FOR PACKING-MACHINES.

Application filed February 27, 1918.

To all wkomz't may concern:

Be it known that I, GEORGE V. Gwrxx. a citizen of the United States, residing at, Brooklyn county of Kings, and State of New York, have invented a new and useful Improvement in Can-spouts for Packing- Machines. of which the following is a specification.

This invention relates to an improvement in can spouts for packing machines, particularly those employed tor the purpose of packing. wrapped tobacco in tin cans.

Certain kinds of tobacco are packed in tin cans each having a cover hinged to the can body on a wire pintle, the metal of body and cover being suitably cut away to form lugs which are interlocked around the pintle to form a hinge. The corners of the can body adjacent the ends of the hinge are some times bent .in slightly, either during manufacture or handling thereafter, and the cans are defective to this extent. Packing machines designed to handle the tobacco to be packed in these covered cans have been provided with a more or less rigid spout upon which the can is telescoped and through which the wrapped tobacco is rammed into the can. These spouts had no provision for handling defective cans, and when an attempt was made to telescope thereon a can having a bent corner adjacent the hinge, the bent corner would catch on the spout and prevent the can from being properly positioned. \Vhen this happened. the machine operator was compelled to stop the machine in order to straighten out the bent corner so that the can could be properly positioned, or to discard the defective can and substitute another. In either case. a production loss resulted. IVhile a bent corner makes a can defective for positioning purposes, it does no harm after the tobacco is placed in said can. It is the main object of the present invention to produce a can spout which will telescope within a can defective to the extent indicated, so that the can may be used without repairs or machine stoppage. lVith this and other objects not specifically mentioned in view. the invention consists in certain constructions which will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, which Specification of Letters Patent.

Patented Oct. 8, 1918.

Serial No. 219,503.

form a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a perspcctive view of a device constructed in accordance with the invention; Fig. 2 is a perspective view of a can with which the s )out is to be used; Fig. 3 is an end view of the structure shown in Fig. 1; and Fig. i is a plan view of the spout tube shown in Fig. 1, but detached from its mount.

Referring to the drawings, 5 indicates a can of the type commonly used in tobacco packing. This can is provided with a cover (5 hinged to the can body on a pintle 7. The upstanding corners of the can body adjacent the hinge ends are marked 8 and 9 and these corners are as before stated sometimes bent inwardly. In order that cans defective as indicated may be used without repairs or machine stoppage, there is provided a spout comprising a tube 10 having a diagonal can engaging end 11, the tube being transversely shaped to tit and telescope within a can. It is the corner 9, when bent, which causes the trouble when an attempt is made to telescope a detective can on the tube, the corner 8 being self-clearing by reason of the engagement of the leading side of the tube behind it as the can is pushed thereon. For the purpose of clearing the corner 9 when bent inwardly, the tube is provided with an inward bend in the wake of said corner, or in other words in the wake of the can hinge end last engaged by the tube. In the preferred constructions, the tube is provided with a longitudinal slit 1'2 and inward bends 13 and 14 alongside said slit. The longitudinalslit makes the tube slightly yieldable at this point and when a detective can is pushed thereon the inwardly bent corner of the can body rides up over the inward bends l3 and 14 into proper position. The inward bends of the tube, being yieldable. do not interfere with the insertion of the wrapped tobacco through said tube into thccan.

-The spout tube is mounted in a well known manner in a holder 15 which forms one link of a chain commonly used in tobacco packing machines.

lVhat is claimed is: v

1. A can spout for packing machines comprising a tube transversely shaped to fit and telescope within a can and having a diagonal can engaging end provided with an inward bend in the wake of the can hinge end last engaged by said tube.

A can spout for packing machines comprising a tube transversely shaped to fit and telescope within a can and having a diagonal can engaging end provided with a yieldable inward bend in the wake of the can hinge end last engaged by said tube.

3. A can spout for packing machines comprising a tube transversely shaped to fit and telescope within a can and having a diagonal can engaging end, said tube being provided with a longitudinal slit and an inward bend alongside said slit at the can 15 engaging end and in the wake of the can hinge end last engaged by said tube.

In testimony whereof, I have signed my name to this specification.
